Key Factors
- 01 Blizzard Warning (Extreme severity) in effect 10 AM Feb 22 through 6 PM Feb 23 for Mercer, Middlesex, Morris, and Somerset Counties
- 02 Total snow accumulation of 18-25 inches forecast; snowfall rates possibly exceeding 2 inches per hour
- 03 Heavy snow begins around 3 PM; blowing snow starting 6 PM with 100% precipitation probability overnight
- 04 Winds increasing to 15-31 mph with gusts to 45-46 mph, causing blowing snow, drifting, and significantly reduced visibility
- 05 Temperatures falling from 36F to near or below freezing (31-32F) in the afternoon and evening, so early rain/snow mix can refreeze into ice
- 06 Wind chills as low as 12-22F; NWS advises travel be restricted to emergencies only

Recommendation
Do not drive today unless it is an emergency. If travel is unavoidable, the only relatively safer window is early morning, roughly 6:00-9:00 AM, before the Blizzard Warning starts at 10 AM (expect wet, slushy roads). There is no safe evening window - from about 3:00 PM onward heavy snow begins and after 6:00 PM blizzard/blowing snow conditions make travel hazardous; if you must move in the evening, do it before 5:00 PM and be off the road by then. Carry a winter survival kit, and if stranded, stay with your vehicle.
